Let's say a VC finances a company that successfully makes cost effective fusion, would it be offset for a loss in such a way that if they had financed one that when on to try and fail the same thing it would work out the same for society?

Lots of finance stuff, like index/underlying latency arbitrage, is really zero or negative sum, but there are parts that aren't.

I agree with that. But isn't the net money that goes from the VC to the fusion company included in the 3% that the article mentions which is adding value by servicing individuals and companies when they need money?

While the argument is that the other 97% of transactions in the finance world add no value. And that 97 >> 3.

That said I don't agree that they add "no value", market efficiency is provided which seems to be a valuable thing in some sense. But i find it quite interesting to think about, especially when you look at them in purely monetary terms as being zero sum.
